Shimano Deore XT BL-M8100/BR-M8120 4-Piston Disc Brake and Lever

The Shimano Deore XT BL-M8100/BR-M8120 4-Piston Disc Brake and Lever set is built for mountain bikers who demand high-performance braking across a wide range of trail conditions. This hydraulic system offers powerful and consistent stopping power, making it ideal for aggressive trail and enduro riding. The BL-M8100 brake lever uses Shimano’s Servo Wave technology, which engages the brake pads quickly and delivers greater modulation for better control. With a stiffer lever design and an ergonomic shape, it offers a more responsive and comfortable feel. Riders can also fine-tune their setup using the tool-free reach adjust feature.

The BR-M8120 4-piston caliper adds even more control, especially on long descents where consistent braking is key. It’s compatible with Shimano’s Ice Tech brake pads, which include cooling fins to reduce heat and prevent brake fade. The caliper also uses a banjo-type connection and inside hose routing for easier setup and cleaner cockpit integration. Whether you’re climbing tight switchbacks or bombing down technical trails, this system gives you the confidence and braking precision to ride harder and safer.

• Servo Wave Technology – Delivers quicker engagement and better modulation for precise braking.

• 4-Piston Caliper – Provides high braking power and consistent performance on steep descents.
